Independent living after fractures in the elderly.

Although fractures are an important source of disability among the growing elderly populations of industrialized societies, patient-centered multidimensional outcome information is scarce. The purpose of this study was to quantify the natural history of recovery from fractures of the upper and lower extremities. From the 1994/95 WHO MONICA survey in Augsburg, Germany, we selected all persons aged 58-78 years who had experienced a fracture during the preceeding 10 years, along with a control population twice as large. The Health Assessment Questionnaire (HAQ) and the Medical Outcomes Study Short Form 36 (SF-36) were administered to these subjects in 1998. Patients' recollection of fracture type and location were validated against medical records. The most recent fracture was in the upper extremity in 45 cases, lower extremity in 55 cases and elsewhere in 46 cases. Extremity fractures resulted in persistent and measurable impairment of the activities of daily living or general quality of life in patients 65 years or older, especially if the femur was involved. More than 40% of the interindividual variation of functional disability in the study group could be explained by age, sex, history of a fracture within 12 years and perceived difficulties walking. Existing generic and specific musculoskeletal outcome measurement instruments thus allow the assessment of functional recovery and health status after fractures in an elderly population. Geriatric assessment following fractures at higher age may improve ability to live independently. Difficulty walking deserves special attention, as it is associated with more general functional disability among the elderly.

[Epidemiology of limb fractures].

To analyze age- and sex-specific frequencies of peripheral fractures, we used data from the third MONICA-Augsburg Survey (1994/95). The study comprises 2404 male and 2450 female participants (age 25 to 74 years) who were questioned regarding fracture history. We investigated fracture prevalence, age-specific incidence rates, and the circumstances under which the fractures occurred. The age-standardized, cumulative fracture prevalence among men (m) 25 to 74 years of age was 45% and among women (w) of the same age 31%. Fracture prevalence among women was more than 10% lower than among men in the younger age groups (age 25 to 64 years), but after an significant increase in the 65 to 74-year-olds the fracture prevalence corresponded to that of men (m: 42%, w: 40%). A peak of incidence rates was found among men at age 15-24 (overall incidence rate: 2017 fractures/100,000 person-years) and at age 45-54 (overall incidence rate: 1640 fractures/100,000 PY), respectively, and among women at age 65-74 (overall incidence rate: 3214 fractures/100,000 PY). The prevalence of self-reported osteoporosis (age 25 to 74 years) was higher in women (7%) than in men (1%). Falls caused 43% (w: 59%, m: 33%) of all fractures, external violence 40% (m: 47%, w: 29%), and sports activities 15% (m: 18%, w: 10%). Further investigation of risk factors related to fractures can contribute to the development of specific preventive measures in that field. In the future, the prevention and efficient treatment of an existing or an often undiagnosed osteoporosis and also the prevention of falls in elderly persons should be an important public health concern.

[DRGs of musculoskeletal diseases: consequences for orthopaedics and accident surgery].

The introduction of the new prospective payment system for inpatient care entails considerable changes for hospitals in Germany. The Australian Refined Diagnosis Related Groups (AR-DRGs), which form the basis for the German system, give the chance to estimate the consequences and implications for the specialty of orthopaedic surgery in Germany. Our study aims at highlighting the most important musculoskeletal diagnoses and to provide an initial economic forecast for them. The comparison with Australian data gives hints for operative and conservative-rehabilitative orthopaedic departments in respect to potentials and focal points for the development of novel patient management tools. The success of orthopaedic departments will depend in the future much more than now on organisational and management issues.

[Regional and sex-specific differences in fulfillment of patient rights: results of a representative population survey in Munich, Dresden, Vienna and Bern].

OBJECTIVES: The European Office of the World Health Organization formulated the Amsterdam Declaration in 1994, demanding thereby the realisation of the principles of a humane health care. These principles relate to the protection of dignity of personhood, to self-determination, the right of information, and the right of quality, continuity and equality in health care. The present study aims at a gender-specific analysis of the fulfillment of these rights. METHODS: Computer-assisted telephone interviews were conducted during the months February and March 2000 in four German speaking European cities (Munich, Dresden, Vienna and Berne). A paragraph of the Declaration on the Promotion of Patients' Rights was regarded as fulfilled if there was at least 80% agreement. RESULTS: Deficiencies were most pronounced for the provision of community and domiciliary services after hospital treatment and for the right concerning humane terminal care and death in dignity. Moreover, regional differences were found between Munich, Dresden and Vienna on one side and Berne on the other side, with degrees of fulfillment being higher in Berne. CONCLUSIONS: In summary, these regional differences are more pronounced than single gender-specific differences, which may be due to chance. Areas with potential for improvement could be identified and can be actively restructured, e.g., in the context of the setting of health targets. An evaluation of the influence of the managed care system which has been established only sporadically in Berne requires more data.

Hip fracture incidence in east and west germany: reassessement ten years after unification.

The rising incidence of hip fractures is of world wide concern. In addition to the demographically aging populations world wide a secular trend of hip fracture incidence has been reported for various populations. The objective of the current study was to reassess hip fracture incidence ten years following German reunification and compare incidence rates in former East and West Germany. Data from the German hospital discharge diagnosis registry were used to compare rates in former East and West Germany. A reassessment of a secular trend was done with directly age-standardized rates of the population 60 years old and over. Significant differences were found between incidence rates in the East and West German states with higher rates in the West. Compared to earlier studies for East Germany, rate in East Germany have increased by on average annually 6% since reunification. This is a steep increase compared to the annual rise by about 3% between 1974 and 1989. Hip fracture incidence in East Germany thereby has doubled during the 25-year period from 1971 to 1996. Although the observed acceleration of a secular trend in East Germany probably has multiple causes, evidence suggests a significant influence of Western life style on hip fracture incidence.

[Evaluation of the appropriateness of hospital care in internal medicine. Reliability of a German adaptation of the procedure].

BACKGROUND AND OBJECTIVE: The evaluation of the appropriateness of hospital admissions and hospital stays has become an increasingly important issue in Germany. Evaluations by the German Physicians Review Organizations (MDS, MDK) demonstrated the need for a standardized, valid and reliable assessment tool for inappropriate hospital use. Objective of this study was to test the reliability of a German adaptation of the "Appropriateness Evaluation Protocol" (AEP). PATIENTS AND METHODS: From the 2317 admissions to medical wards of a teaching hospital in Hessia in 1997 we randomly selected 52 patients to test the inter-rater-reliability (54% female, mean age = 66 years +/- 18). Another 49 patients were randomly selected to test the intra-rater-reliability of the AEP (53% female, mean age = 61 years +/- 20). We estimated general agreement, specific agreement and Kappa statistics for the agreement of the evaluation of hospital admissions and hospital days. 95% confidence intervals were reported. RESULTS: The German adaptation of the AEP showed an inter-rater-agreement of 92% (88-96%) for hospital admissions and 76% (73-80%) for hospital days. Correspondingly, we observed an intra-rater-agreement of 96% (88-100%) for hospital admissions and 93% (91-95%) for hospital days. The high agreement was independent of the length of hospital stay and independent of the proportion of inappropriate hospital days. CONCLUSION: A standard instrument for the assessment of the appropriateness of hospital care with known metric properties may be useful for quality management in hospitals and provide competitive advantages in a consolidating health care market. The AEP could be such an instrument.

[Validity and reliability of proband recall of fractures].

The validity and reliability of patient recall of diseases depends on the kind of disease. The validity and reliability of patients' recall of fractures was assessed among the 146 cases of a nested case-control study on independent living following fractures in the elderly. On declaration of a fracture a letter was sent to the general practitioner requesting medical information on the latest fracture receiving treatment. A total of 99 medical discharge letters (68%) could be collected for further evaluation. The information on fracture localisation which was obtained both during the patients interviews 1994/95 and 1998 and through the medical discharge letters were coded with reference to the AO (Arbeitsgemeinschaft für Osteosynthesefragen)-classification and compared. The Kappa-statistic for the reliability of patient information was 0.80-0.89, and 0.77-0.89 for the validity, depending on the degree of specified concordance. Obtaining information on fractures from patients appears as a valid and reliable source of epidemiologic data. Patients who generally are affected physically or had to stay in a hospital due to a fracture or its treatment seem to have a good recall of this event. It appears that it can be remembered years after the event with sufficient reliability and validity.

[Health and human rights--development of a questionnaire for measuring perceived human rights status].

Health and human rights as interlinked concepts are a promising new avenue in public health. The aim of this study was the development of a reliable and valid instrument for the measurement of the human right status. The reliability and validity of this new questionnaire for human rights (HRS = human right scale) was measured within a group of Public Health students (n = 42) and the participants of the KORA-fracture-study. Test-retest-reliability was 0.73 (ICC: 0.69) and Cronbach's alpha was 0.66-0.79. The evaluation of the validity with the help of a factor analysis and a reconstruction study pointed out, that the perceived human rights status has to be treated as an interlinked and not divisible concept. Both study groups showed deficits for items in the dimension justice and participation.

[Reproducibility of a German scale for assessing the need for inpatient treatment in surgery].

During the past years, the assessment of the appropriateness of hospital utilization has become increasingly important in the German health care system. Previous evaluations by regional review organizations in several states demonstrated the need for a standardized, reliable, and valid instrument to evaluate the appropriateness of inpatient care. Objective of the study is to test the reliability of a German adaptation of the "Appropriateness Evaluation Protocol" (AEP). Among all 2672 admissions from the department of surgery of a regional medical center during one calendar year, 54 patients were randomly selected to evaluate the inter-rater reliability and 51 patients to test intra-rater reliability. Overall agreement, specific agreement and Kappa statistics were estimated for every hospital admissions and all consecutive hospital days. The German AEP showed an inter-rater agreement of 74% (62-86%) for hospital admissions (Kappa = 0.44) and 84% (79%-88%) for all hospital days (K = 0.55). Intra-rater reliability was 88% (79%-97%) for hospital admissions (K = 0.60) and 88% (85%-92%) for all hospital days (K = 0.70). The observed agreement is independent of length of hospital stay and proportion of appropriate days. A standardized instrument with known metric properties is essential for quality management in hospitals to prepare for an increasingly consolidating health care market in Germany. The German AEP is a reliable instrument, which will allow to identify inefficiencies in the management of surgical inpatients.

Violence and fear of violence in East and West Germany.

The purpose of this research was to assess the effect of major social changes in Germany since 1989 on mortality due to intentional injury. Mechanisms and types of fatal intentional injury in East and West Germany between 1970 and 1995 were determined from death certificates and compared with judicial data on violent crime convictions and recent public survey data on citizen fear of crime. The number of homicides among East German males increased between 1989 and 1991, and the homicide rate remains high when compared with West German males (although lower than that of American males). Homicide among German females is less common, presently about equally likely in East and West. Violent crime in general has become more frequent in Germany, and citizen fear of crime has increased markedly, especially in the East. Non-citizens are convicted for an increasing number of homicides and assaults. Rates of suicide were declining in East and West before reunification, and these rates have continued to decline. Social changes in Europe since 1989 have led to noticeable increases in violence and homicide in Germany, which in turn have reduced feelings of security among German citizens, especially in the East. Suicide rates have not been affected.

[Corroboration of concurrent assessment of inappropriate hospitalization with retrospective evaluation based on patient records].

BACKGROUND AND PURPOSE: Since the availability of a German adaptation of the "appropriateness Evaluation Protocol" (AEP) for hospital utilization review, physicians and health care managers were concerned about a potential overestimation of the extent of inappropriate hospital use in a retrospective assessment. The objective was to assess the agreement of concurrent and retrospective assessment of inappropriate hospital use. METHODS: The appropriateness of 42 admissions to surgical wards in a teaching hospital was tested concurrent to the admission. In 25 hospitalized patients the appropriateness of hospital days was assessed. Results were compared with the retrospective testing of the same patients after three months. RESULTS: Agreement between concurrent and retrospective assessment within the same reviewer was 86% of admissions (95% CI = 75%-96%) and 96% of hospital days (88%-100%). Kappa showed values of 0.85 and 0.78, which can be described as excellent. A comparison of two different reviewers, one testing concurrently, the other retrospectively showed agreements of 86% and 90%. The proportion of inappropriate days was the same in both designs. CONCLUSIONS: The results refute prior concerns that a retrospective assessment of the appropriateness of hospital use is impossible because in a retrospective design important clinical information would remain unconsidered or clinical information not yet available at that time would be used for the evaluation. The possibility of an incorrect assessment due to a retrospective design is within the variability inherent to the instrument. Despite the strong agreement, the small sample of surgical patient limits the generalizability of results.

[Incidence of operations in Germany via telephone survey in 4 selected cities].

Considerable regional variation of surgical procedure rates has been reported for a number of countries. Influential variables that have been discussed are patient-related, physician-related and health care system-specific factors. A representative computer-assisted telephone survey was conducted in four selected regions for a study sponsored by the German Federal Ministry of Health. These regions were the townships of Aachen and Hamm in North Rhine-Westphalia and Chemnitz and Görlitz in Saxony. During the telephone survey 1897 persons were contacted and 1041 interviews completed. Multiple logistic regression showed a surgical procedure frequency which was by 40% higher in Aachen than in Hamm. During further analysis the regional localisation was replaced by region-specific structural health care information variables. During this analysis the regional frequency of medical specialists was significant at a 5% level (odds ratio: 1.07; 95% confidence interval: 1.02-1.12). This result can be interpreted as an increase in surgical procedures by 7% for each additional specialist per 10,000 persons. However, no definite conclusion can be reached based on the available data. Intensifying the presented survey-based health services research has the potential to identify regional over- or undersupply of medical services, to objectify and accompany informational, administrative or political action and thereby to support equity in access and health care in the sense of an optimized allocation of resources.

Injury mortality in East Germany.

OBJECTIVES: This study determined the effects of social changes in East Germany since 1989 on patterns of injury mortality. METHODS: Death certificate data regarding injuries from 1980 through 1995 and police data regarding traffic injuries in East Germany from 1980 through 1998 were compared with similar data from West Germany. RESULTS: The number of motor vehicle-related injuries and deaths in East Germany increased dramatically between 1989 and 1991, whereas those in West Germany declined slightly. The increased mortality in the more rural East has especially involved young men driving automobiles on rural roads and has persisted since reunification of East and West Germany. Falls, other accidents, and suicides have shown no such effect. Homicide among East German men has increased but remains uncommon. CONCLUSIONS: Recent social changes in East Germany, including increased access to motor vehicles and decreased restrictions on personal freedom, have been associated with increased motor vehicle crashes and mortality, especially among young men and on rural roads.
